Any reliable dentist in Da Nang?

I have recently contacted a couple of dentists in Da Nang. They offered me to solve my problem in 10 days. What they didi not know is that I am well aware of what my problem is, and this is something that must be done in many stages through a few different procedures that need months of healing time in between to get everything done in perhaps a year or longer. In other words, I might had contacted "professionals" with no regard of my problem, but an obvious interest in my money, or I might have failed to convey my problem with clarity as well, however I discard this option, as they were given a full and recent cone beam scan of my whole mouth.

Anyway, has anyboy had good experiences with dentists in this city? Any other city perhaps? Mind to share your experience and recommend a honest dentist? One of those who rather give you bad news detrimental of losing a potential costumer/income? 

Btw, this problem requires a few different surgery techniques before implanting.

Thanks in advance
